Delete one or more columns starting at the specified column.
AI agents call delete_sheet_columns to permanently remove resources in Excel MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes columns from an Excel worksheet, which cannot be undone by the tool itself. If an AI agent misuses this tool with incorrect column indices, it could irreversibly destroy significant amounts of data. While the impact is limited to a single worksheet, the data loss is complete and unrecoverable through the tool's normal operation, warranting a Destructive classification with high severity.
From the tool's definition delete_sheet_columns deletes one or more columns starting at the specified column. The verb 'delete' combined with the operation of removing columns indicates irreversible data destruction.
